Specification of Letters Patent.

Application filed March 1. 1M3.

Patented ti ep't. 1145,1913. Sc1ialNo."/51,395.

To all 1117:0122, it may con/writ Be it known that l, Eases-r Huntrunny, a citizen of the United States, residing at New Britain,Ilartford county, State of Connecticut, have invented certain new and.useful Improvements in Cutting Devices of which the following a full,clear, and act descri pt ion.

This invention relates to cutting devices, and more particularly to afolding cutter of the type embodying a blade holder sec tion and a guardsection pivotally connected thereto and designed to receive and protectthe cutting edge of the blade which projects from its section.

The present invention aims to provide a simple folding device of thischaracter, of compact structure and especially designed to protect the bade portion of the device from injury. llhese and other advantages arefully described in the following; speci fication, taken in connectionwith the ac companying drawings forming part thereof and illustrating apreferable embodiment of the invention.

In these drawings: Figure 1 is a view in front elevation of the cutting,'device with the parts folded together. Fig. 2 is a view in frontelevation of the parts extended, with the cutting blade exposed readyfor use. Fig. 3 is a view in end elevation of the parts shown in Fig. 1.Fig. 1- is a from mentary View in elevation of the folded deviceillustrating the locking means em ployed. Fig. 5 is a fragmentarylongitndi' nal sectional View taken through the device when folded.

Referring to the drawings by numerals, 1 indicates a blade guard in theform of a metal clip, this clip being of U-shape or channel crosssection and being formed preferably of sheet metal bent upon itself. Oneend of this clip is preferably rounded and has the bottom of its channelcut away as at 9 to permit the attachment of the other portion of thecutting device. This portion comprises a blade holder formed of a metalclip 3 of channel or U-shaped cross section and having an end -t offsetat substantially right angles thereto and inserted within the recessedend of the channel clip 1. This holder clip 3 receives one edge of acutting blade 5. preferably of the wt: for type, which blade extendssubstantially the e tir le gth of the clip, preferably to a pointclosely ad- -\vhen the parts are moved .of its offset 4 will jacent theotlsct end thereof. The bladercceiring portion of the clip 5' terminatesrelative to its offset end 4- so as to bring! the adjacent side (ftltIt.of the blade 5 within the recessed channe end 3, of the guard clip 1 atall times. The overlapping}; ends of the two clips are pivotallyconnected together by means of a rivet stud 6 having its end upsetagainst. a washer 7 located on the side of the clip opposite the rivethead. The recessed end of the guard clip 1 overlaps and incloscs theadjacent side edge of the blade 5 at all times and maintains said bladein the plane of the channel of said guard section at all times, guidingit therein from extended into folded position and retaining its edgewithin said channeled portion when the parts are extended, this beingpossible because said blade edge is positioned adjacent the point ofpivotal connection of said ovcrlapping ends. By providing one of thesesections with an end offset at approximately a right angle therefrom andpivotally connected to the recessed end of the other section, the twosections may be folded to bring their edges closely adjacent andparallel to each other and in the same plane so that a very compactstructure is afforded. l urthermore, it will be noted that when theblade section is fu ly opened, the rear edge rest against the edge ofthe guard section adjacent the recessed end 2. and that this will takethe load strain 011' the pivot stud and locking projection hereinafterdescribed.

In order to provide means for detachably locking the parts in extendedosition or when the blade-holding section is unfolded for use and fordetachably locking said parts in folded position, I have providedsockets 8 in the recessed pivoted end of the guard section 1, thesesockets being located at diametrically opposite points radially of thepivot 6. Cotiperatingwith the sockets are projections 9 carried by theoffset end 4 of the blade holder section and positioned to snap into oneor "the other of the sockets 8 when the blade holder section is movedfrom folded to unfolded position. This affords a frictional lock,sufficient under ordinary circumstances to hold the parts in opened orclosed position. there hemg sufficient clearance between thcinclosedsides of the channel clip -1- and the offset end 4 to permit theprojections 9 to spring out of the locking sockets 8 when the parts areswung from one position to another.

The blade holder and guard sections are preferably made of stamped sheetmetal, the locking recesses and projections being readily stampedtherein, The cutting blade 5 is preferably of the thin safety razortype, making the device very thin and compact when folded.

While I have herein described a specific embodiment of the invention, itshould be understood that the same may be altered in detail and relativearrangement of parts within the spirit of the invention and. the scopeof the appended claims.

What I claim, therefore, and desire to secure by Letters Patent is:

.1. In a device of the character described, in combination, a clip ofchannel cross section having one end offset and extending atsubstantially a right angle, a second clip of channel cross sectionhaving one end overlapping the oii'set end of said first clip, one ofsaid clip ends being recessed to receive the overlapping end of theother, means for pivotally connecting the overlappingends of said clipsand a blade seated within one of said clips with one edge extendingto apoint adjacent the point cl pivotal interconnection of said ends wherebysaid edge is maintained at all times within and is guided by theoverlapping end of the other clip 2. In a device of the characterdescribed, in combination, a clip of channel cross section'having oneend offset and extending at substantially a right angle, second clip ofchannel cross sectioirhaving one end overlapping the offset end-0t saidfirst clip, one of said clip ends be'i recessed to receive i 7 I I V thepverlapping end of the other, means tor pivotally connecting theoverlapping ends of said clips and a blade seated Within one of saidclips with one edge extending to a point adjacent the point oi? pivotalinterconnection of said ends whereby said edge is maintained at alltimes Within and is guided by the overlapping end of the other clip, theedge of the recessed clip adjacent its recessed end providing a bearingabutment for the adjacent edge of the other clip when the parts aremoved to fully opened position.

3. Ina device of the character described in combination, a blade-holdingclip ofchannel cross section having one end otiset and extending atsubstantially a right angle, a second and guard clip of channel crosssection having one end recessed to receive and overlap the otl'set endof said first section, means for pivotally connecting said over lappingends, and a blade seated in said first clip with its cutting edgeprojecting therefrom to seat in said guard clip, "said blade beingpositioned in said first clip to bring one edge adjacent the point ofpivotal connection of said ends whereby said blade edge is maintained atall times within and guided by the overlapping end of said guardsection.

d. In adevice of the character described. in combination, ablade-holding clip ct channel cross section having" one end oilset andextending at substantially a right angle. a second and guard clip ol?channel cross Lion having one end recessed to receive and overlap theoilset end of said first section, means for pivotally connecting saidoverlapping ends, and a blade seated in said first clip with itscutting); edge projecting theretrom'to seat in said guard clip, saidblade being positioned in said first clip to bring one edge adjacent,the point of pivotal connection of said ends whereby said blade edge ismaintained at all times within and guided by the overlapping; end ofsaid guard section, and cooperating locking means on said overlappingends for locking said clips in folded and opened positions.
